Air and Gas Blowers

Universal RAI® blowers are heavy-duty rotary blowers designed with detachable rugged steel mounting feet that permit easy, in-field adaptability to vertical or horizontal installation requirements.

Because of the detachable mounting feet, these units can be easily adapted to any of four drive shaft positions: right, left, bottom, or top. The compact, sturdy design is engineered for continuous service when operated in accordance with speed and pressure ratings.

The basic model consists of a cast iron casing, carburized and ground alloy steel spur timing gears secured to steel shafts with a taper mounting and locknut, and cast iron involute impellers. Oversized antifriction bearings are used, with a ...

Basic Blower Description
Ram™ rotary blowers are heavy-duty units designed with integral-shaft ductile iron impellers having an involute profile. The headplates and rigid, one-piece casing are grey ...

ROOTS offers conventional factory blower package systems with optional equipment as detailed below. ROOTS also provides fully-engineered, packaged blower units specifically designed to meet exacting customer requirements.

Casing: The cylinder and headplates are manufactured from high grade cast iron.
Impellers and shafts: Impellers are ductile iron with integral shafts. All sizes are dynamically balanced to close tolerances. The shaft diameter of machines in the XLP range is larger than that of similar designs, allowing increased operating pressures to be achieved without increasing blower size.
Bearings: Cylindrical roller bearings are used, and are sized to give long operational life. In addition to their normal duty of carrying radial loads associated with the differential air pressure on the rotating impellers, these bearings provide axial ...

Basic Blower Description
RAM™ WHISPAIR™ rotary blowers are heavy-duty units designed with integral-shaft ductile iron impellers having an involute profile. WHISPAIR blowers reduce noise and power ...

The basic model features a cast iron casing with a computer-designed cast relief for noise and shock suppression, carburized and ground alloy steel spur timing gears secured to steel shafts with a taper mounting and locknut, and cast iron involute impellers. Oversized anti-friction bearings are used, with a cylindrical roller bearing at the drive shaft to withstand V-belt pull. Detachable rugged steel mounting feet permit easy in-field adaptablility to either vertical or horizontal installation requirements.
